It’s being here now that’s important. There’s no past and there’s no future. Time is a very misleading thing. All there is ever, is the now. We can gain experience from the past, but we can’t relive it; and we can hope for the future, but we don’t know if there is one.

In science it often happens that scientists say, ‘You know that’s a really good argument; my position is mistaken,’ and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn’t happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
